Hello,
You can use a QQ plot to visually test if 2 continuous variables are from the same distribution and you get a straight line. Is there a way to visually test if 2 discrete variables are from the same distribution? Also is there a way to test it mathematically? Thanks

You can do a QQ plot for discrete data, but it's a bit more tricky, i'll try to find a source for you.

Hi there,
Apart from using a QQ plot is there any other way to test if two variables have the same distribution? Thanks

A chisquare test?
